0.6.3

Agent Skills 0.6.3 sharpens code review, adds two new reference checklists and an honest comparison doc, and introduces a set of guardrails that steer new-skill work away from duplication, plus a wave of community fixes and polish.

Highlights

• Deeper code review. code-review-and-quality gains structural-depth lenses (reduce-don't-relocate, a named Structural Remedies catalog, a file-size gate, and finding prioritization), and its severity labels now line up with the skill's own taxonomy. (#304, #302)
• Two new reference checklists. An observability checklist (on-call questions, RED/USE metrics, symptom-based alerting) and a project-wide Definition of Done. (#240, #317)
• How it compares. A new docs/comparison.md puts agent-skills side by side with Superpowers and Matt Pocock's skills, with a link to a controlled head-to-head. (#300)
• Guardrails against duplicate skills. A CONTRIBUTING pre-flight checklist, a path-scoped .claude/rules/ guardrail, a PR-overlap guideline, and validator/CI upgrades that enforce naming, description triggers, and command-description parity. (#301, #313, #325, #323, #270, #255)

Skills, commands & references

• git-workflow-and-versioning: add release and versioning guidance (semver, tags, changelog). (#334, @HMAKT99)
• spec-driven-development now delegates task mechanics to planning-and-task-breakdown. (#303, @nucliweb)
• planning: document the tasks/plan.md and tasks/todo.md output paths. (#337, @hiyochi)
• browser-testing: default to an isolated profile. (#239, @federicobartoli)
• debugging: fix the step range. (#293, @shihyuho)

Fixes & polish

• Use repo-relative script paths (drop the old /mnt/skills/user/ form). (#307, @creazyfrog)
• Fix the Gemini /ship agent path. (#306, @creazyfrog)
• Explain the expected "commands/ ignored" plugin warning, and clear the underlying lint without breaking Antigravity. (#305, @creazyfrog; #273, @CollabxConstruct)
• Antigravity code-simplify reads AGENTS.md. (#288, @Dashsoap)
• Make helper scripts executable. (#289, #276, @Dashsoap)
• hooks.json path fallback for manual installs. (#269, @worldfunction4)
• Move agents/README.md to docs/agents.md to fix a custom-agent frontmatter warning. (#260, @nucliweb)

Docs & CI

• Document the /webperf command and setup. (#247, @Bortlesboat; #268, @CooperSheroy)
• README and getting-started tidy: list orchestration-patterns, add code-simplify. (#290, #283, @Dashsoap)
• Standardize actions/checkout to v6. (#275, @Dashsoap)
